The platform B is hung on weighing-beams The construction of the registering device D, connected at their inner free ends with N (shown in detail in Figs. 4, 5, and 6) is as the head E of a rod E, extending through a follows: A transverse shaft N is journaled in 5 5 tube F' into a box F, secured on the frame the casing N and on the rear end of the said A and containing oil or "other liquid. shaft is secured a star-wheel N adapted to The inner or lower end of the rod E is conbe turned by equidistant projections L on the nected with a scale-spring G, attached at its front face of the clutch-wheel L. On the lower end to the piston H of a dash-pot I, supshaft N, within the casing N is secured a I00 ported by rods I and a cross-head I from the pinion N", in mesh with a gear-wheel N said rod E. The downwardly-extending pismounted to rotate loosely on the shaft N and carrying on its face a pin or stud N provided with a pointer N indicating on the dial N fixed in the casin g N The several parts are so proportioned that a whole revolution of the clutch-wheel L imparts a full revolution to the star-wheel N and pinion N, so that the gear wheel N is turned to move the pointer N a distance on the fixed dial N to indicate one hundred pounds, and if the clutch-wheel makes but one-fifth of a revolution the gear-wheel is turned to move the pointer N over the dial N to indicate twenty pounds. As shown, the number of arms on the star-wheel N correspond to the number of projections L on the clutch-wheel, and the dial is graduated to record a minimum weight of twenty pounds; but it is evident that the several parts can beso proportioned and arranged that any desired amount in weight measure can be registered by the tally N. The dial N is secured on the stud N and is graduated upv to two thousand pounds or one ton. The pin N on every revolution meshes into and turns the wheel N held on the stud N and carrying the unit-ton wheel N read through an opening in the fixed dial N as shown in Fig. 6. A pin N on the wheel N turns on each revolution of the latter. A wheel N mounted to rotate loosely on the stud N and carrying the tens-of tons wheel N is likewise read through an opening in the dial N A pin N on the hub of the wheels N N serves to rotate the wheel N", carrying the hundredsof -tons wheel N Thus, as shown in Fig. 6, the aggregate weight of the loads that have passed over the platform B is one hundred and sixty-one tons.

The clutch-wheel L is fitted to slide on its bearing and is engaged by a shifting arm 0, secured on a vertically-disposed shaft 0, journaled in suitable bearings in the box F and passing through a tube F therein, as indicated in Fig. 1.

On the upper end of the shaft 0 is secured an arm 0 drawn on by a spring 0 so as to normally hold the clutch-wheel L in mesh with the face of the pulley K, so that when the latter is rotated a rotary motion is given to the wheel L, and the motion of the latter is transmitted to the registering device N to indicate the proper weight of the merchandise that passes over the platform B.

In order to throw the clutch-wheel out of engagement'with the pulley K, I provide the following device, controlled from the merchandise (J as the latter passes over the end of the platform B: The arm 0 previously mentioned, is pivotaliy connected by a link P with an arm P, secured on a shaft Q, journaled in the frame A near the exit for the merchandise C, as shown in Figs. 1 and 2. The shaft Q carries a tripping-lever R, which extends down into the path of the merchandise C, so that when the latter moves off the platform it imparts an upward-swinging motion to the said lever B, whereby the shaft Q is rotated and the arm P, the link P, and

arm 0 impart a rotary motion to the shaft 0', so that the shifting arm 0 moves the friction-wheel L out of engagement with the pulley K. As soon as the merchandise C has passed over the platform the lever B returns to its former position by swinging downward, and. the spring 0 acting on the arm 0 causes a turning of the shaft 0 to cause the arm 0 to move the friction-wheel L back into engagement with the pulley K.

Now it will be seen that by the arrangement described the merchandise passing over the platform B is weighed and the mechanism is reset upon the merchandise leaving the platform, so that the scale is ready for weighing a second piece of merchandise delivered to and passing over the platform B, as above described.

The tubes F and F for the rod E and shaft 0 prevent the liquid contained in the box F from escaping in case the weighing-scale is tilted while being shifted from one place to another. It is understood that the spring G always returns the pulley K to its previous po sition as soon as the merchandise slides over the platform B and previous to the clutchwheel again engaging the said pulley K.

It will also be seen that by the arrangement described the machine is self-adjusting or balancing, so that an accumulation of dirt or pieces of merchandise does not affect the proper weighing of the merchandise passed over the platform B.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. A weighing-scale, provided with a pulley adapted to be turned from the weighing-beams, a registering device, a clutch mechanism for actuating the registering device from said pulley, and a tripping device controlled by the merchandise, for throwing the clutch mechanism out of engagement with the said pulley, substantially as shown and described.

2. Aweighing-scale, eomprisinga platform, weighing-beams carrying the said platform, a spring-pressed rod connected with the said beams, a rope and pulley connected with the said rod for turning the pulley,upon the beams being actuated by the merchandise passing over the platform and a registering device operated from said pulley, substantially as shown and described.

3. A weighing-scale, comprising a platform, weighing-beams carrying the said platform, a spring-pressed rod connected with the said beams, a rope and pulley connected with the said rod for turning the pulley,upon the beams being actuated by the merchandise passing over the platform, a weight-registering device, a clutch mechanism adapted to engage the said pulley and adapted to actuate the registering device, and a tripping-lever in the path of the merchandise as the latter leaves the platform, the said tripping-lever controlling the said clutch mechanism, substantially as shown and described.

4. A Weighing-scale, provided with a rod connected with the weighing-beams supporting the platform, a spring connected with the said rod and attached to a dash-pot piston, a spring-pressed cord carried by the said rod, a pulley engaged by the said cord, and a clutch mechanism for actuating the registering device, and adapted to engage the said pulley to be rotated by the latter, substantially as shown and described.

5. A weighing-scale, provided with a rod connected with the weighing-beam supporting the platform, a spring connected with the said rod, a dash-pot having its piston con nected to said spring, a spring-controlled cord carried by the same rod, a pulley engaged by the said cord, a registering device engageable with said pulley to be rotated thereby, and a tripping-lever in the path of the merchandise actuated to disconnect the pulley and registering mechanism by the passage of the merchandise, substantially as described.

6. A weighing-scale provided with a weighing-platform, a registering device, operative connections between the platform and registering device, and a tripping device controlled by the merchandise passing over the platform and temporarily breaking said operative c011- nections, substantially as shown and described.
